my winchester M70, loved the lighter loads. 130 gr. also try a couple of different manufactures ammo. My M70 in .270 loves federal fusions. my Ruger in .270 shoots Hornady the best. both in 130 gr.

shot guns i believe you pull the trigger, with rifles you must squeeze the trigger. there could be all kinds of reasons, bullet choice being only one of them.

| | Suggestions for shooting tighter groups
Here are some ideas for a new rifle shooter to try..
1. Drop down to a 50 yard range if it's available. Just until you get comfortable shooting your rifle. If they aren't almost touching at 50 why go to 100 yards.
2. Use sand bags from the bench to stabilize the rifle. If your cross hairs are moving your groups are going to be staying over 3 inches at 100 yards.
3. Limit yourself to 20 rifle shots per a visit to the range. Bring your shotgun along and shoot a round of skeet/trap after shooting the 20 through the rifle.
4. Verify everything is tight with your scope rings and mounts.
5. Have a friend that won't give you to much grief shoot your rifle if the group size doesn't shrink. Just be ready to be beat with your own rifle.
6. Your rifle or scope could have mechanical issues that will keep it from shooting real small groups even after you address the above issues. Your crown on the barrel could be bad, rifle's bore could be rough, scope could be loose on the inside or allow the cross hairs to drift.
7. Relax, keep telling yourself that this all about having fun. Alot of deer have been killed by shooters that couldn't shoot better then 3 inches at 100 yards.

Great suggestions KL!!!
But I do have a question about groupings with a rifle of mine.
Have a 6mm Remington with a 4 rd drop magazine. After getting sights adjusted at ~ 50 yds, I move to the 100 yrd range.
Out of the 4 round clip, 3 rds will be close (within 1 1/2 inches) but one of the rounds would go high, about 4 or 5 inches high. Don't ask which round of the 4 went high. I repeated this through 3 different magazines. 3 rounds close, 1 high.
Anyone have any suggestions besides stopping at 3 rounds? <grin>
(Proved it drops deer with 1 round during the past season.)

Thanks for the suggestion, Ronn. I do tend to head for the range in late summer to early fall, which is typically during the warmest months of the year around here. The longer wait between rounds would allow the barrel to cool some before the next round goes through.

I start with a large cardboard back board 30 x 30 and start at 25 yds. I shoot two then adjust, shoot two and let the gun set. Move to 50 yds and shoot two make any adjustments and fire 1 more. Move to 100 yds and shoot two, make any final adjustments, let the barrel cool and then shoot two for final sight-in. I am always concentrating on grouping the holes and making adjustments from the two shot group. I like front sand bags and solid bench to shoot from.Generally for PA deer hunting I set the final shot group about 1.5"high.
